AI Thread Summary
Gravitational potential can be zero only at an infinite distance from any gravitating body, while gravitational field intensity can be non-zero in various locations. A spacecraft traveling from Earth to the Moon was suggested as a scenario, but it was clarified that at a point between the two bodies, the gravitational potential would not be zero. The potential at that point would always be negative, indicating that gravitational potential cannot be zero while still experiencing a gravitational force. The discussion emphasizes the distinction between gravitational potential and field intensity in the context of celestial mechanics. Understanding these concepts is crucial for solving related physics problems.

Gravitational Potential is zero and gravitational field intensity is non-zero.

Work out the potential of an object that is in between Earth and moon at a distance of 81.25 times closer to the moon than to the earth. Work out the force on the object at that point.Mandavi said:

I think I may have misled you. The gravitational force can be zero where there is non-zero potential. But I don't think you can have zero gravitational potential and still have a gravitational force.
At the point which I suggested between the Earth and moon, the potential will not be zero. My error. The potential will always be less than zero. The only place where gravitational potential is zero is an infinite distance from any gravitating body.

Here is what I tried
This question was actually asked in one of our engineering entrances.
The answer was 1D.
My teachers say that we have to use μₘ/fₘ to get to this answer. I cannot understand why. I'll be really glad if you could tell me the exact definition of power (numerically) that works in all scenarios.
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance)
My thoughts for the first case , one of them must be 12 volt while the other is 0
The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears.
My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it.
I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height.
But the...
